About this surface
Alpinous Onyx
Faint outlines in beige and soft grey trace rounded, cloudlike shapes over a pale white surface, echoing the layered look of onyx. The markings are delicate and low in contrast, so the slab stays bright and quiet.
Questions
About Alpinous Onyx
Alpinous Onyx is an engineered quartz surface: crushed natural quartz bound with polymer resin and pigments. It is a manufactured material, not a natural stone. iStone does not publish a breakdown of its material here, so we cannot quote a percentage.
Our listing shows Alpinous Onyx in a polished finish and 20 mm and 30 mm thicknesses. Our listing shows a polished finish and 20 mm and 30 mm thicknesses; iStone's website does not state them for this colour, so we confirm the finish and thickness in your quotation. Your quotation states the finish and thickness we have priced.
For everyday cleaning use a soft cloth with warm water and a little mild washing-up liquid, and wipe up spills promptly. Use a chopping board rather than cutting on the surface, a trivet or heat mat under hot pans, and avoid bleach, abrasive pads and harsh cleaners.
Alpinous Onyx costs £375–£550 per m², supplied, fabricated and installed. Your quotation is itemised and depends on your worktop and location.
RT Stone, which supplies iStone, describes a 15-year warranty that is conditional on installation by an iStone Certified Fabricator, registration within 30 days and the original invoice. Its website and warranty letter differ on scope, so we do not state a length until RT Stone confirms it. Stoneone's 2-year workmanship guarantee is separate, and we confirm the warranty that applies to your order in writing.
